To all 'whom t may concern a Be it known, that I, WILLIAM E IARML.s'rEAD, a citizen of the Unitedl States, residing at Sandersville, inthecounty of.v Washington and State of Georgia, have invented ,certain new.and useful Improvements -in Apparatus for Manufacturing Ice; and I do.hereby declare the following to be a full;

h 4\'clear, and exact descriE tion of the invention,

same.

This invention `relates to improvements in an apparatus forxmaking clearand pure ice rom raw water, and the present invention is directedespecially to improvements in ending August 22, 1910, but is alsoapplicable to other forms of ice making apparatus. f The principalobject of the invention is to provide means for insulating the inlet andoutlet lnozzles ,leading the water to and drawing it from the iceforming cans to prevent freezing of the water in the nozzls. vf.

Another object of the invention is toprovide means for vcausing an evenow 'of the brine around the ice forming cans from top to bottom thereof.

With the above and other objects in Vview the invention consists incertain combinationsand arrangements of theparts hereinafter described,and the novel features .thereof will be particularly4 pointed out inthe. appended claims.

Forl a clear understanding of. the` inven tion, reference will be hadlto the accomf panying drawings illustrating a preferred embodimentthereof, and in the Ldrawing like characters of 'reference indicatecorresponding parts. Figure 1 is a longitudinal sectionfthrough thebrine tank, the rest of the a paratus be ing shown inJ elevation; Fig.is a detail sectional viewpon an enlargedescale-of 'the y thel brinetank is anoutlet pipe 6 having.

ball and socket', connection and Fig. 3 is a similar .view of thevoutletio'r suction nozzle. In the drawings 1 represents a brine tank Yprovided at one end with a brine supply A pipe 2 entering near thetopand terminating in a downwardly turned vertical ontion 3 havingan openlower end 4 and' so a plu. rality of apertures 5 through its sides.Entering near the bottom at .the other end of asjwillenableot ersskilled in the artv through freezing therein insulation means asfolblock of wdod h an' upwardly extending portion 7 fopen at its top endtions 9. By pipes site ends of the brine tank and providing thesidesofthe-pipes with perforations, an

even iiow and distribution ofth'e brine around the ice formmg cans fromtop to bottom thereof is obtained. The inletand foutlet pipesareconnected the usual' manner to a brine circulating pump and brinecooler, neither of which 1s shown. VEX- tending fromthe outlet pipe 6 isa pipe leading to -a storage tank not shown. vThe ,pipe 6a is providedwith a shut oii` Vvalve 6", and when it is de'sired to withdraw thebrine from the tank the-valve is opened and the brine permitted to liowto the storage tank.

Arranged -in spaced relation to the bottom of. the brine tank is a4layer of insulating material 10, and below said insulating material-is'disposed' a pipe- 11 which extends from'one. end of the brine tank asat12. The insulating material 10 is apertured as at 12*L for-receiving thevertical nipples 13 of the T fittings 14 andthe end elbow 15 of the pipe111. Each nipple 13, Fig. 2, has threaded therein a ball member'ladaptdto form a tight joint by contact with a member 17- having asemi-cylindrical socket .18. lThe 1socket member `17 -is provided with aange 19 which is secured'by bolts or rivets 20 orl other suitable meansto the bottom -of each ice forming can 21. l

In order to prevent the water passing the ball and socket members fromlows isV provided'z--The ball members 16 are made hollow for theirentlre length-and provided with insulation 2,1 preferably a aving anopening 22 therethrough. The'center of vthe socket .menifbers 17 arealso hollowed out from their semi-cylindrical sockets 18for' the rest oftheir `length and the bottoms of the' ice forming cans 2O 'are providedwith alining openings 23. Insulation 24 similarsto thatdescribed isinserted1 in the hollowed out portions of the socket members 17 andppenings '23 preferably iush with the inside'of the/bottoms of the iceforming cans andlsame is provided with apertures 25. A space 26 is leftbetween the insulating material 21` and. 24 toallow for the properseating of and clearance between the ball members 17 inthesemi-cylindrical sockets 18. The ball members 16 of the couplings shouldproject a suili'cient height above the bottom of the brine tank, 'topermit them to project well above the surface of any brine that mayremain in said tank after.

The ice tops in alinethe brine has been drawn olf.

have their in the divisional plates.

A cover for the brine tank is pipe 31 the cover.

shutl by the water in w'ood 37, Fig.

mitting the upper end a ing cans by means of a the pipe 44 to the .pipe

pump extends a pipe ter 46.

From the foregoing it is apparent' that n the brine will iow evenly fromtop to bottom around the ice forming cans thus' pro-t- `viding an equalamount of freezing land the vdili'erent cans will be completelyfrozenand vfor harvesting at the same time; and' 'then the brine may bereadily withdrawn xfrom the tank. At that time the members 16 of thecoupling will project up above the surface gf the insulatingbottom ofthe tank, and any'brine adhering tp said bottom canready designated by30 and is adapted to rest on the top-edges of the ice forming cans forlocking same in' position. Arranged above theicover is a similar to theypipe 11 having'the same kind 'of T fittings 32 and end elbow fitting 33,the downwardly extending nipples 34 of which project through apertures35 arranged above each ice forming can in Short pieces of pipe ornozzles 36 depend from the nipples 34. and vtheir open ends extend alittle below the top edges v of the ice forming cans 21. The nozzles 36are insulated and prevented from freezing the ice freezing cans, byfitting inside each nozzley a blockv of 3, or other suitable insulatingmaterial which is provided with an f aperture 38. The apertures 38are'in vertical alinement with the'apertures 25 through the bottom ofthe ice forming cans for perlcirculation of 'the water therein.

The extending end 12 of the pipell is provided with a T fitting 39A fromwhich .projects a vertical pipe 40 carrying at its filter 41 having itstop edge substantially in alinement with the upper forming cans tomaintain /level inthe cans. The pipe with a source of water supiceforming cans, and said with a-shut-ofl'f valve 42. lled the valve 42 isflow upwardly through the center of the ice formcirculating' pump 43connected by a flexible connection and 31; and from said 45 terminatingin a suitable discharge connection into -thelilnot reach the openings insaid members,` thus preventing any of the brine fromnding its way intothe pipe 11, and 'contami- -nating the raw water. As the inletandoutletI nozzles are insulatedthe freezing of the water thereinisprevented.- L
